Concept Search - What can I type?

For a concept search, you can enter phrases, sentences, or full paragraphs in English. For example, copy and paste the abstract of a patent application or paragraphs from an article.

Concept search eliminates the need for complex Boolean syntax to inform retrieval. Our Semantic Gist engine uses advanced cognitive semantic analysis to extract the meaning of data. This reduces the chances of missing valuable information, that may result from traditional keyword searching.

No mechanism currently exists in DIA
whereby a recipient's
enterprise can notify the originator's enterprise that the
originator's distribution has been discarded due to the distribution
being considered obsolete. Current notifications of undelivered mail
to an originator of a distribution are contained in the Un-Delivered
Mail Log Status Document.

By providing
a value in the "Notification Code" field of the
Un-Delivered Mail Log Status which represents that the document has
not been delivered to the recipient, because the recipient's
enterprise considers the document obsolete provides the capability of
notifying the originator of the distribution that the distribution
has not been delivered.

Using this
mechanism permits an enterprise to be aware of which
distributions were actually delivered to a destination. Furthermore,
an originator who wishes to notify a recipient that a distribution is
obsolete can be notified as to whether the distribution was discarded
before the recipient accessed the distribution.
